"NFCLINK" software with MSP-EXP430G2

Hello,

I want to use the "nfcplayer.exe" in "NFCLINK" software with my MSP-EXP430G2 LaunchPad + DLP-7970ABP, but, I can't.

I flashed the example code (http://www.ti.com/lit/zip/sloc297) with CCS to the LaunchPad, And, I installed the "NFCTOOL" software in the PC. And then, I configured the configs of the software. I launched the "nfcplayer.exe" (Ran as Administrator) in the NFCLINK, clicked "Start NFC" botton. The application said "NFC: Start FAIL" I'm sure the LaunchPad and DLP-7970ABP are working. And, I installed the driver in the PC.

What happened?

The logs are:

20:19:02:521 CNfcPlayer::nfcStart: Enter 20:19:02:522 CNfcPlayer::nfcStart: Global NFC flags: 0xF8EFF9F7, L1 flags: 0x00050030 - will be ignored if local (configuration-specific) flags are set 20:19:02:523 CNfcPlayer::nfcStart: No local TRACES.NFC parameter found - adding global or default parameter 20:19:02:523 CNfcPlayer::nfcStart: No local TRACES.L1 parameter found - adding global or default parameter 20:19:02:523 CNfcPlayer::nfcStart: Initialization <READERTYPE=TRF7970 IOTYPE=SERIAL PORT=COM3 TRACES.NFC=f8eff9f7 TRACES.L1=00050030> 20:19:02:523 CNfcInstance::nfcStart: Enter 20:19:02:523 CNfcInstance::nfcStart: NFC library loaded 20:19:02:523 CNfcInstance::nfcStart: NFC API version: 2.4 20:19:02:523 CNfcInstance::nfcStart: NFC stack version: 16.1.153.0 20:19:02:545 CNfcInstance::nfcStart: NFC controller initialized 20:19:02:546 CNfcInstance::nfcStart: !

Moving this question to the NFC/RFID Forum.

sloc297 does not have or use a GUI, it has backchannel UART output to terminal

what you need to do is either get an MSP430F5529 LaunchPad to use with your TRF7970A BoosterPack and use correct software for that MCU (i.e. NFCLink(NCI) or NFCLink(Standalone)

or use the hardware you have and make it do what you want it to automatically, and have the terminal output to PC.

Hello Chun,

The example code for the MSP-EXP430G2 LaunchPad does not work with any TI GUI interface. You can use a UART terminal (PuTTY, Docklight, Termite) to see the tag data being read.

To use the NfcPlayer, you will need to get an MSP-EXP430F5529LP and Flash with CCS Uniflash the .out file for the LaunchPad example that comes with the NFCLink install.

Hello!

How can I do to make it as a NFC writer?

Best regards,

Hello Chun,

Do you want write NDEF data to tags (such as what would be read out by NFC Smartphones)? Which tag type(s) do you want to write data to?

Hello,

I want to write to any type of tag, if it is supported.

Best regards,

Hello Chun,

You will want to get the MSP430F5529 LaunchPad to do this:

With that, you can either use the NfcPlayer GUI you mentioned before or use our TI NFC Tool GUI from our Reader/Writer App Note: http://www.ti.com/lit/an/sloa227/sloa227.pdf

Hello,

So, it can't works as a NFC writer with MSP-EXP430G2?

Best regards,

Chun -

yes it does, its embedded code on a value line MSP430 - so you would be limited by the flash memory and RAM - a good combo really from both a price and benefits for simple and direct RFID or NFC like operations - further, if you want to be in charge of things in your application and just need specific functionality - please see slides 14 and on (in the attached) for example using Type 2 tags - for one protocol example

4035.NFC Forum Type 2 Tag Platform Operations with TRF7970A_02_2014.pdf

Types 3, 4A/4B and Type 5 tags also supported, in addition to several proprietary card types.

Hello,

Sorry, but I still don't understand what's it says.

it means its not fancy with GUI, but you must write your application as you wish, or move up the MCU launchpad hardware chain

Hello,

Can you teach my how to code to make it work as a writer? (i.e. write, format ,earse, etc...)

Best regards,
Chun Nan

Hello Chun,

There are basic API's for tag writing for Type 2, Type 4A, Type 4B, and Type 5 already included.

You would need to leverage these API's to write custom application which would handle writing to these tags yourself.

Also, Type 3 would require the creation of a new function to handle writing.

You mention write/format/erase - by Format do you mean Format for NDEF messaging? Such as what Smartphones use to read tags?

If so, please bare in mind that properly handled NDEF applications are complex in nature in order to properly identify tag sizes, handle failures, and ensure the message format is accurate. If you want to do NDEF messaging, the G2553 may end up being too small for your application.

Currently only a rudimentary NDEF example is included for Type 4A and Type 4B, but it won't read large messages and cannot handle any errors which can occur.

If you want to handle NDEF applications and also re-use existing TI resources, both firmware bases I referred to come with tag writing capability built in for NDEF message.

Hello,

So, no anyway to make it work as a writer easier, or work with the GUI?

Best regards,
Chun Nan

Hello Chun,

How hard or easy it is to add Writer depends on how broad the support is. Writer for one technology without NDEF could be very simple. Writer for all technologies including NDEF would require a lot of firmware.

GUI support with any existing GUI's is a no. The two GUI's we offer with full tag writing capabilities are designed specifically for their firmware bases and will not work with any other firmware base.

NfcPlayer is for NFCLink
TI NFC Tool is for sloa227 firmware from www.ti.com/lit/an/sloa227/sloa227.pdf

They will not work with other platforms.
